Cable waterproof tips


Everyone knows that water in the cable is a very serious problem. Sometimes you think that you have done a good waterproofing measure, but the cable is still getting water. So how does the cable get water? Let me introduce to you the causes and countermeasures of water ingress in cables.


1. When storing: the newly purchased power cable is sealed with plastic sealing sleeves at both ends, but after a period of use, the rest is wrapped in plastic paper, and the outside is tied with a rope. The tightness is not good. Water vapor will seep into the cable.


2. When laying the cable: When laying the cable, the cable head wrapped in plastic paper is sometimes immersed in water to allow water to enter the cable; when pulling and piercing the pipe, sometimes the outer sheath is broken.


3. After laying: the cable head is not made in time, and the unsealed cable port is exposed to the air for a long time, or even immersed in water, so that a large amount of water vapor enters the cable.
